Three important aspects of the preparation of SrTiO3 thin films by MOCVD are discussed in detail in view of the application of these films as the capacitor dielectric of Gbit-scale DRAMs: CVD reactions in the Sr(DPM)2-Ti(i-OC3H7)4-O2 system, step coverage and relations between microstructure and electrical properties.…

In this study poly(β-hydroxybutyrate) (PHB) was used as a spreading material to form LB monolayers at the air-water interface. Isotherms were found to show a transition at about 14 mN/m that is argued to be associated with a phase transition in the monolayer. Stable monolayers could be obtained at various surface pres…
We have undertaken a study of the propagation of carriers in one-dimensional (1D) aperiodic systems within the tight-binding scheme under the action of electric fields. We have concentrated on the Fibonacci (F) and Thue-Morse (TM) lattices, which are of great practical importance since these structures can be fabricat…

The kinetics of the displacive cubic‐to‐tetragonal ( c → t ′) phase transformation and the evolution of twin structure of Y 2 O 3 ‐ZrO 2 systems were investigated by employing the time‐dependent Ginzburg‐Landau equations, in which the displacive modes were described by nonconserved order parameters. The original elast…
Graft copolymerization of methyl methacrylate (MMA) or 2-hydroxyethyl methacrylate (HEMA) onto poly(3-hydroxybutyrate) (PHB) and its copolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate) {P(HBHV)} was carried out by using simultaneous radiation and preirradiation techniques from a 60Co γ-rays source. Degree of grafti…
Abstract Solvent swelling of natural rubber composites, containing both untreated and acetylated short sisal fiber, has been investigated in a series of normal alkanes such as pentane, hexane, heptane and octane. The restriction on elastomer swelling exerted by sisal fiber as well as the anisotropy of swelling of the…

<111>-oriented tin-doped indium oxide (ITO) films were deposited by rf magnetron sputtering on ZnO-coated glass substrates (ZnO/glass). The ZnO underlayers were also deposited by rf magnetron sputtering and have been known to exhibit <001> preferred orientation in a wide range of deposition conditions. The…
In this paper we describe the preparation and preliminary characterization of diblock copolymers with a low surface energy block. These polymers were prepared by modifying the isoprene block in styreneisoprene-based block copolymers with either short perfluoroalkyl or dimethyl siloxy ‘fingers’. Specifically, the dien…
Phase development during reaction hot pressing of α‐Si 3 N 4 , AlN, Al 2 O 3 , and M 2 O Z powder mixtures (M = Li, Mg, Ca, Y, Nd, Sm, Gd, Dy, Er, and Yb) forming α′‐SiAlON has been studied. The wetting behavior of the ternary eutectic melt of M 2 O z ‐Al 2 O 3 ‐SiO 2 was found to control the reaction sequence during…

Abstract A new class of polyanhydrides synthesized from nonlinear hydrophobic fatty acid esters, based on ricinoleic, maleic acid, and sebacic acid, possessed desired physico‐chemical and mechanical properties for use as drug carriers. The polymers were synthesized by melt condensation to yield film‐forming polymers w…
